The ink-jet marking process offers several unique opportunities for producing quality hard-copy images. There are, however, certain limitations and requirements of the technology that must be taken into account when developing imageprocessing procedures and algorithms for ink-jet printing systems. This paper describes a number of issues that set ink-jet apart from many of the other marking processes. For example, ink-jet can be treated as a truly "binary" marking process. Thus, single isolated pixels are easily and reproducibly formed on the marking substrate. Halftoning procedures have been developed that take advantage of this attribute to produce more gray levels for a given resolution. Ink coverage on paper, however, must often be limited to < 200% . Also, the perceived color will be dependent on the order in which the colors are delivered to the marking substrate. Examples illustrating these and other concerns are given. Optimal image-processing procedures for the ink-jet marking process can be developed based on an understanding of these and other ink-jet specific issues.
